, STANCIIION.

Application led November 23, 1909. Serial No. 530,414. n

To all who-mit my'concern: y

Beit known that I, AHENRY L. FEnRIs, a citizen of the United States,residing at Harvard, in the county of McHenry and State of Illinois,have invented a new 'and useful Improvement in Stanchions,of which ,pthe following isa specification.

My: invention -.relates to new and useful Improvements -In stanchi'ons,andv 1s fully described and explained in the specification f .n andshown 'in the accompanying drawing, in which- Figure 1`is an elevationofmyimprovedl stanchion showing the position which the parts occupy inuse, and, In' addition, In

dotteddines, amovable side in its open position; Fig. 2 is a detailedtransverse section 'of the upper portion of the stanchi'onnthe closedposition being indicated in solldlines and the o en position in dottedllnes; kFlg.

3 is a. section on the line 3 of Fig. 2; Fig. Il:v

re secured the supportingfchains of the" stanchion, andthe said'brackets arefadjustL able uponV their respective tubes in order that thestanchion may be at all times properly balanced, whatever be theposition of itsstationary, but adjustable, sides.

C is the stationary side of the stanchion,

the same being formed'of an outwardly fac'- ing met-al channelif-l beamof U-shaped cross 4section secured to the top and bottom of the if?stanchion by bracket c, held in place by set v sizes.

screws and capable of adjustment to accommodate thest-anchion to animalsof different As this stationary side is adjusted it will be obvious thatthe center of gravity of the'stanchion will be shifter-h and it is topermit the stanchion to be sup ported at all times in line with thecenter 'of gravity that the brackets a, b are made adjustable. D is themovable side oi the stanchlon,

which,y is made in the form of au outwardly-A opening channel bar, thecornersof which 'wir s o'i U-shapein cross-section, in order il arerounded so that the narp corners shall be brought in conact with thenecks of the animals held by `the stanchion.` The Patented Aug.; 1911ipivotal supportof thewmovable sideof-the V stanchion 1s furnishedby'a-bracket al, rightangled in form, one endv of which isy introf'duced into the correspondingA end `O the .`botto1n-tube `A ofthestanchion, and they other end of which is turned Vup .and pivl otedbetween the flanges vvof the movable member D of the stanchion.

stanchion lies a locking-bar E, at the end v 'of which is adownwardlyfturned hook e Within the tube B at the top offthel and whichis provided, ata distance from i that' hook, with an upwardly-projectingshoulder e1. The locking-bar is provided with a downwardly-extending`handle E1,

which is slotted at e2, a pin e3 ext-ending through said slot and beingsecured between .flanges of the channel-bar which forms the .movablemember D of thestanchion. The

handlel ljll'is'cast with a bore e* which recelveswithin it a spring e5,the tendency of which is to rotate the locking-bar and its handle aboutthe pivot formed by the pin e3 1n such a direction as to press the lfreeend of the locking-bar downward, and when the handle is depressed itwill be evident that the spring will be compressedV and the hooke tube Bis traversed near that end adjacent to the movable member of 'thestanchion by, a

pin F in position-to be engaged by the shoulder e1 upon the locking-bar.

The ,operation of the device will now be Jreadily apparent. W'hen thedevice is closed, pressure upon the handle will disengage the hook atthe end of the locking-bar from the end of the. upper member of thestanchion with which it normally engages, per? mitting the movablemember of' the stanchion to be swung outward laterally, so Vthat ananimals head can pass between the side lmembers of the stanchion, either1n entering :or leaving. The device can be closed with the greatest easeby simply pushing the movable member inward, and in such closingl the.locking-bar will, of course, be continuously guided by the tube'withinwhich it lies, so that no manipulation is necessary in closing thestanchion eXcep-t to push the movable member. The engagement of the pinF with the shoulderupon the locking-bar obviously prevents the movablemember from swinging open too far. ,I

The device is advantageous because of its end' ofthe locking-bar raised.The

simple construction,- because 4of the adjustable features embodied init, and because the locking-mechanism is entirely closed and iscontinuously: guided by the inclosing-tube from its open. position toits closed position.

It is thus apparent that no matter how loosea singleand simplemanipulation;

I realize that considerable variation is possible in the details ofconstruction of my lmproved device, Without departing from the spirit ofmy invention, and I do not intend, therefore, to limit myself to thespecifioform herein shown and described.

, What I claim as new and desire to secure by Letters Patent is y y Y Ina stanchion, tubular top and bottom bars, slidable brackets on saidbars, a side bar connected to said brackets, means forseslot and pinconnection` therewith and the bottom bar, a locking bar adapted to'passthrough -saidtop bar and having a handle portion mounted on said sidebar and having curing said brackets in adjnstedlposition, aj, secondside bar-pivoted 'at its lower end to vided at its forward end with ahook adapt- 1 ed to engage the outer end'of the top bar,

a shoulder in the rear of said hook,.a stop adjacent .the forwardend ofsaid top bar wherewith said shoulder is adapted to engage in thewithdrawal movement of said locking bar', aspring-carrying bore on said,

handle located below 4ite slotted connection with lthe side bar, aspring in said bore, whereby the hook end of said locking bar is causedt-oengage the outer end of the tubu lar top bar, and to be disengagedtherefrom when said handle is depressed, Lfor the pur pose Set forth.4
